Moving to South Carolina on Medicare, and living on a hurricane coast

South Carolina is one of the country’s big retirement destinations: the Lowcountry around Hilton Head and Bluffton, the Grand Strand from Myrtle Beach to Georgetown, the Charleston suburbs, the York County towns south of Charlotte, and the lake country around Columbia and Greenville. Many of the people we help did not turn 65 here; they arrived here on Medicare from Ohio, New York, New Jersey, Pennsylvania or Florida. The Medicare rules for a move are not complicated, but they are unforgiving, so here they are plainly.

What moves with you, and what does not

The relocation Special Enrollment Period

Medicare Advantage and Part D plans are sold by county, and you must live in the plan’s service area. A permanent move outside it gives you a Special Enrollment Period to join a plan where you live now. If you tell your old plan before you move, the window opens the month before the move and runs two full months after it; if you tell it afterward, you get two full months from the month you tell it. What counts is your permanent residence — the address on your driver’s licence and your tax return — not a five-month stay at the beach.

The Medigap door that opens when you leave an Advantage plan

This is the part most people miss. Federal rules give you a guaranteed-issue right to buy certain Medigap plans without medical underwriting when you leave a Medicare Advantage plan because you moved out of its service area. The window is short — generally 63 days after the old coverage ends — and in South Carolina it is worth more than in a birthday-rule state, because once it closes the only other way into a supplement is medical underwriting. If you are arriving on an Advantage plan and have any thought of a Medigap policy, decide before the window closes, not after your first winter. The state-by-state rules are on switching Medigap plans.

Snowbirds, half-backs and two homes

Plenty of people keep a place here and a place elsewhere, and plenty of Florida retirees move “halfway back” to the Carolinas. The rule is the same in both directions: a Medigap policy with Original Medicare works with any provider in the country that accepts Medicare, in both states, all year. Most Advantage HMOs cover only emergencies and urgent care outside their service area; some PPOs cover routine care out of network at higher cost; a few plans carry a travel benefit for extended stays. If travel is the reason you are choosing an Advantage plan, we get the benefit in writing from the Evidence of Coverage before you enroll. Our Florida section and Minnesota section cover the same question from the other end.

Hurricane season and your Medicare

Once you live on the coast, storms are part of the calendar. Medicare has a set of rules that switch on when the President or FEMA declares an emergency or major disaster, and they are worth knowing in June rather than in October.

• The disaster Special Enrollment Period. If you were eligible to make a Medicare enrollment decision during a valid window — the Annual Election Period, the Medicare Advantage Open Enrollment Period, your Initial Enrollment Period, or another Special Enrollment Period — and a FEMA-declared emergency or major disaster kept you from making it, you get a Special Enrollment Period to make that decision afterward. It applies to people who live in the declared counties and to people who rely on someone in those counties to help them enroll. It does not give you a second bite at a decision you made on time; it gives you the bite you missed. Hurricane Helene in September 2024 brought a public health emergency and disaster declarations to South Carolina counties, and the SEP with them.
• Early refills. Once an emergency is declared for your area, Part D plans must allow early refills, cover fills at out-of-network pharmacies when yours is closed, and relax prior-authorization rules for medications you already take. Get a refill as soon as a hurricane watch is posted; pharmacies close before the warning.
• Care when you evacuate. Original Medicare and a Medigap policy work anywhere in the country, so an evacuee in Atlanta or Charlotte is covered as if at home. Medicare Advantage plans, during a declared disaster, must cover care from out-of-network providers at in-network cost-sharing when in-network care is unavailable and must waive referral requirements. That protection ends when the declaration does.

Becoming a South Carolinian on paper

When the move is permanent — licence, voter registration, tax return — you choose from the plans sold in your new county, and the menu in Beaufort or Horry County is not the menu you left. Our agency is licensed in South Carolina and fifteen other states, including North Carolina, Georgia, Ohio and Minnesota, so we can move your coverage cleanly in either direction; for Florida, our Florida section’s own licensed agent takes over.
